OPERATING PRECAUTIONS

This is a multi-fuel, direct-fired, forced air heater. It's intended use is primarily temporary heating of buildings under construction, alteration or repair.

1-K kerosene is the recommended fuel due to the refinement to elliminate contaminants. Other fuels such as #1 or #2 fuel oil, JP8, and #1 and #2 diesel can be used but, do not burn as clean as 1-K kerosene. Additional ventilation should be considered when using fuels other than 1-K kerosene.

Direct-Fired means that all of the combustion products enter the heated space. Even though this heater operates very close to 100 percent combustion efficiency, it still produces small amounts of carbon monoxide. Carbon monoxide (called CO) is toxic. CO can build up in a heated space and failure to provide adequate ventilation could result in death. The symptoms of inadequate ventilation are:

• headache

• dizziness

• burning eyes and nose

• nausea

• dry mouth or sore throat

Be sure to follow advice about ventilation in the Safety Precautions section.

Forced Air means that a blower or fan pushes the air through the heater. Proper combustion depends upon this air flow; therefore, the heater must not be revised, modified or operated with parts removed or missing. Likewise, safety systems must not be circumvented or modified in order to operate the heater.

When the heater is to be operated in the presence of other people the user is responsible for properly acquainting those present with the safety precautions and instructions, and of the hazards involved.

SAFETY PRECAUTIONS

1.

Check the heater thoroughly for damage. DO NOT operate a damaged heater.

2.

DO NOT modify the heater or operate a heater which has been modified from its original condition.

3.

Use Kerosene, JP8 Jet Fuel, #1/#2 Diesel, or #1/#2 Fuel oil.

Never use gasoline, naphtha, paint thinner, alcohol or any other non-approved fuels .

4.

For indoor use only. Not for use where exposed to weather.

5.

Use in well ventilated areas, provide at least 2 sq. ft. (0.19 sq.

2.

Follow all of the "Precautions".

3.

Fill the fuel tank with clean kerosene, JP8 Jet Fuel, #1/#2

Diesel or #1/#2 Fuel Oil. In extremely cold weather, condensation may develop in the tank and it is recommended that a tablespoon of de-icer be added for each gallon (4 liters) of fuel in the tank. When filling the heater, use at least

2 gallons (8 liters) of fuel. Be sure heater is level and do not overfill. Use a funnel or can with a long fill spout.

IMPORTANT: Before filling fuel tank the first time or after extended storage periods, drain the fuel tank of any moisture or condensation.

4.

Locate heater at a safe distance from combustible materials. Models 50K & 75KT are not suitable for use on wood floors or other combustible materials. When used, the heater should rest on suitable insulating material at least 1 inch thick and extending 3 ft. or more beyond the heater in all directions.

HEATER START UP

Operating Instructions and Owner’s Manual 04/07 70276 Rev.C

MAINTENANCE AND STORAGE

WARNING. To prevent personal injury, unplug the heater from the wall outlet before servicing.

For maximum efficiency and trouble-free service, make the following periodic maintenance, cleaning and inspections.

DAILY SCHEDULE

1.

GENERAL. Make general visual inspection of heater for loose or damaged parts. Check nuts and bolts to insure against looseness caused by vibration or rough handling.

Damaged parts should be repaired or replaced before using heater again. Check heater operation to be sure it is operating normally (See "Servicing" section for description of normal operation).

2.

FILTERS. Dirty air or fuel filters will cause an imbalance in the air-fuel mixture. The best indication that this condition exists is an increase in odors or difficulty getting your heater to ignite. This heater should never be operated without the filters in place. If required, clean filters as described under "500 Hours" and "Annual Schedules".

500 HOUR SCHEDULE

1.

AIR INTAKE FILTER. Remove and wash the filter element with a mild detergent, dry thoroughly and replace. Do not oil the filter element. If your heater is used where there is considerable dust or dirt, clean as often as necessary

(approximately every 50 hrs.).

2.

REMOVE DUST. Clean heater twice a season (more often under dusty conditions). Remove accumulated dust from the transformer, burner, motor and fan blades with compressed air. Wipe area clean with a clean dry cloth.

Inspect area to insure all foreign materials are removed, especially around the burner and combustion area.

3.

CAD CELL. Clean the glass portion of the cad cell with a soft dry cloth.

4.

NOZZLE. Accumulation of dirt from fuel and carbon from the compressor vanes will eventually fill up the passages in the nozzle, resulting in reduction of fuel and air flow.

Pressure will gradually increase giving improper fuel-air mixture and excess odor and smoke. If this occurs, replace the fuel nozzle.

5.

FUEL TANK. Clean twice a season (during frequently used periods, clean twice a month). Drain and flush the fuel tank with clean fuel oil.

ANNUAL SCHEDULE

1.

AIR OUTPUT FILTER. Remove the air output filter and tap the contaminated side gently on a solid object to remove contaminates. Compressed air or liquids should not be used to clean this filter. Reinstall cleaned filter in filter body in the same position as it was when removed. If the filter appears extremely dirty, replace it with a new filter of the same type. When replacing the filter cover, be sure the gasket is firmly in place and the screws in the filter cover are tight to prevent air leaks.

2.

FUEL FILTER. Remove the fuel filter from fuel line and direct compressed air through the filter in the opposite direction of fuel flow. Safety glasses should be worn when using compressed air.

3.

AIR AND FUEL LINES. If the air or fuel lines are removed during cleaning, be sure all connections are tight before operating unit.

4.

AIR PRESSURE SETTING. The air pressure has been properly set at the factory. If the air pressure is out of adjustment, it will most likely be caused by dirty air filters, a partially plugged nozzle, an air leak in the system or improperly set pressure. If adjustment becomes necessary, first determine the proper pressure setting for your heater which is printed on the serial label located on the fuel tank. With a full fuel tank, remove the plug (part #33 from the exploded-view drawing on page 9) from the air filter cover and attach a 0 -

15 PSI pressure guage. Start the heater and note the pressure reading. If the pressure is low, slowly turn the pressure adjusting screw in (Clockwise) until the correct pressure is obtained. If the air pressure is high, turn the adjusting screw out (counterclockwise) until the pressure is correct. When correct pressure is reached, unplug the heater, remove the gauge and replace the plug.

STORAGE

Store the heater in a dry location free from fumes or dust.

At the end of each heating season, clean the heater as described in the MAINTENANCE section. Drain and flush the fuel tank with clean fuel. The manufacturer recommends completely filling the tank with fuel for extended storage to minimize condensation inside the tank.

SERVICING

A hazardous condition may result if a heater is used that has been modified or is not functioning properly.

When the heater is working normally:

* The flame is contained within the heater.

* The flame is essentially yellow.

* There is no strong disagreeable odor, eye burning or other physical discomfort.

* There is no smoke or soot internal or external to the heater.

* There are no unplanned or unexplained shut downs of the heater.
